Whitehorse strips the Klondike staircase down to one face-up card in each of seven columns and puts forty-five cards in the stock. The stock is turned three at a time and may be turned over as often as you like, so nothing is ever lost — but the moment a column empties it is filled at once from the waste, or from the next cards turned off the stock if the waste is bare. You never choose what lands in a space. The game is about steering that fill: arranging the waste so that the card it hands you is one you wanted.
Look at the waste before you empty a column. The top card of the waste is the card that will fill the space — always. If it is a card you can use as a column base, empty away. If it is a low card with nothing to build on it, clear the waste first, or turn the stock until a better card is on top, and only then make the move that opens the space.
Every third card is the one you can reach. Turning by threes means that on a straight pass only every third card is playable; the two beneath it are visible but locked. Playing a card off the top changes which cards the next pass will offer, so a single tableau move can bring the whole stock into a new alignment. When the stock is stuck, look for any move that shifts it by one.
Unlimited redeals are not unlimited time. You can turn the stock forever, but if no move on the board changes and the waste comes round in the same order, the game is over, and this version tells you so. A stuck stock is a stuck game; the way out is always a tableau move, never another click.
Build long runs, not tall columns. With every column starting from one card, spaces open constantly and the fill keeps feeding them. Long alternating runs on a few columns are worth more than short ones everywhere: they travel as a unit, they open spaces, and they give the fill somewhere to put its cards.
The Klondike family turns a handful of the same dials — how much is hidden, what an empty column accepts, how many cards a click turns, how often the stock comes round — and Whitehorse turns three of them at once. Nothing is hidden, the draw is three with no limit on redeals, and the space rule is replaced by a forced fill borrowed from the Forty Thieves line. Its nearest neighbour is Saratoga, which is Klondike face up with draw three and unlimited redeals; Whitehorse is Saratoga with the staircase flattened and the spaces taken out of the player's hands.
